faulty channel mappings on Intel ICH6

Thanks for reporting the bug. Which sound manager are you using? (Alsa..etc?)

Dave Thacker

I'm not with the system right now, but it's a default Edgy install. So
that should mean it's ALSA, right?

Please attach as files:
ls -l /proc/asound/cards to
The output from the lspci command
The output from the dmesg command
The output of cat /proc/version

You may also want to have a look at https://help.ubuntu.com/community/DebuggingSoundProblems to see if there is any othe relevant info you can provide.
Thanks! DaveThacker

Same problem on feisty (also on a dimension 5000):

The output from the dmesg command

The output of cat /proc/version

Hope this helps

Same problem here, but with sis966 onboard sound (snd-hda-intel). KDE does the mapping well in feisty (same as in windows and as the colors should go), gnome gets it totally wrong though.
Anything changed around this bug?

I am having a similar problem on Hardy beta. The master volume seems mapped to the headphone output. The headphone output appears to be bass/treble or perhaps one of the 3D controls, it's hard to tell.

Yes it's still the same with Hardy Beta (sis966 chip here). Left and right are okay but the center and rear boxes are coming from the front ones (not sure which exactly, kinda mixed into all of them).

I so much hope this will work once again in Hardy as nicely as it did in Fesity :)

This is a hardware routing issue on many AC'97 codecs and can be worked around via alsa-lib. It is NOT an alsa-lib bug.

And we fix the problem how exactly?
Any documentation on how to "work it around via alsa-lib"?
You know, just so we can actually fix the problem if it's not working in Ubuntu by default anymore :)
Thx!

Not sure how Intrepid handles this though, will have to wait those 2 weeks or so until release..

hi, having sound conf problem too. I can't choose outputs together as I could done it before the upgrading. the System/Preferences/Sound is no longer as easy to configure as it was before. sound disappears with 2.6.31-19 and cames back with the 2.6.31-20'.

I think the problem comes from this impossible multi selection of outputs. I tried many conf and all outputs work but not together.
